Abstract
1H NMR spectra of benzene, salicylaldehyde, 2-nitroaniline, 4-nitroaniline and 4-aminotoluene have been measured in 13 solvents. The solvent-induced changes in chemical shifts of the proton signals of these compounds have been correlated with refractive index and relative permittivity (D) by the Rummens equation extended by the term f(D) = ((D - 1)/(2D + 1))2.
